OIL-BURNER.

Specification of Letters Patent.

Patented time. a, rare.

Application filed April 17, 1918. Serial No. 229,008.

To all whom it may concern:

Be it known that I, ARTHUR A. a citizen of the United States, residing at Seattle, in the county of King and State of WVashington, have invented certain new and useful Improvements in Oil-Burners, of which the following is a specification.

This invention relates to improvements in oil burners and has for its principal object to provide an improved and novel burner device for use with ranges, stoves and the like; to provide a burner of the class briefly described which is adapted to burn medium heavy oil. Another object of my device is to provide new and novel means for superheating the fuel before it is -iignited and to provide an adjustable means or regulating the mixture of fuel and air, My device is particularly designed for use with ranges and stoves 111 that it is portable and is adapt ed to set within the fire box of the range. Still another object of my'device is to provide an adjustable and tapered sleeve means for regulating the mixture of gas and air and the area of combustion.

Other objects will appear as my invention is more fully explained in the following specification, illustrated in the accompanying drawings and. pointed out in the appended claims.

In the drawings, Figure 1 is a side elevation of my device with parts broken away.

BAILEY,

Fig. 2 is a sectional end elevation taken along line m-m of Fig. l.

Referring more particularly to the drawings, numeral 1 indicates fire box walls of a range and 2 the stove covers of the range. The burner proper is set within the fire box and embodies a base casing 3 which is provided with a pair of similar burner passages 4 throughout its length. Slots 5 are cut 1n the top of the burner passage and perm t of the discharge of the charge of fuel and an in the shape of thin sheets of flame. Between the burner passages 4 a depression 6 is provided in the base casting for the purpose of holding fuelfor warmmg up the device upon starting. The rear end of the base casting is turned up in the form of an L and the burner passages 4 are united into a common opening which leads to a mixing and superheating pipe 8 which is bolted to the turned up portion of the base casting. It will be understood that the mixing pipe is located directly above the base casting and in spaced relationship thereto.

. The mixing I a tapered pipe 8 is provided with an open bell end within which a fuel discharge nozzle extends and from which the air for combustion is drawn. A fuel supply pipe 9 is located directly below the mixing pipe and above the base casing and after passing forwardly in this position, it is turned up as at It) and is provided with a valve 11 which is d rectly in front of the open end of the mixing pipe. Valve 11 is provided with a discharge orifice 12 through which the fuel is arrayed into the mixing pipe. It will be understood that the pipe 9 is in an area of intense heat and that the fuel is heated to ayaporizing oint in its passage toward a discharge needle valve 11 and that it leaves a small orifice 12 in the needle valve 11 in the form of the vapor and that it is mixed with air which enters the mixin pipe 8 through the bell 8 and around t e inner end-of the valve 11. After entering the mixing pipe 8 the fuel charge passes through sleeve 13 which is adjustably mounted within the end of the pipe 8 adjacent the hell 8. By moving the tapered sleeve 13 to just the proper point, it has been found that the proper portion of air is mixed with the gas and that the mixing is so regulated so as to limit the formation of carbon deposits and the clogging of the slots. This is animportant feature of applicants device and has been found to operate successfully with this slidable sleeve' and unsuccessfully without it. The fuel supply pipe 9 is partially filled with small woven wires 15 in' order to offer a resistance to the flow of fuel through the pipe and to prevent an excessive amount of circulation and separation of the fuel while passing through the heating supply pipe.

While I have shown a particular form of embodiment of my invention, I am aware that many minor changes therein will readily suggest themselves to others skilled in the art without departing from the spirit of connected burner passages within the said base casting, transverse slots in the said base casting and communicating with the burner casting and at its end in alinement with the axis of the mixing pipe, whereby the fuel is sprayed into the mixing pipe, and means for adjusting the supply of air which enters the mixing pipe.

2. In a device of the class described, the combination of a base casting, a plurality of connected burner passages within the said base casting, transverse slots in the said base casting and communicating with the said burner passages, whereby the fuel is discharged from the burner passages, a mixing and superheating pipe connected to the said base casting and communicating with the said .burner passages, a tubular and internally tapered sleeve slidably mounted,

within the mixing pipe and adjacent the open end thereof, whereby the charge of fuel is regulated as to the proper amount of casting and the mixing pipe,

memos? air and the mixture of air and gas before entering the burner passage.

3. In a device of the class described, the

combination of a base casting, a pair of communicating and similar and parallel burner passages within the said base casting, an L- shaped extension on the said base casting, a mixing and superheating pipe connected to the said extension and communicating with the said burner passages, said mixing pipe being parallel with and in spaced relationship with the said base casting, a fuel supply pipe positioned intermediate the base said pipe having an opening at its end in alinement with the center of the mixing pipe, a slotted sleeve within the open end of the said mixing pipe, whereby the supply of air to the mixing pipe may be regulated, a plurality of parallel and transverse slots in the base casting and communicating with the said burner passages, whereby the fuel after 'being mixed with airin the mixing pipe and passin through the combustion chambers is disc arged and ignited on either side of and beneath the fuel pipe and mixing pipe.

In testimony whereof I afiix mysignature.

ARTHUR A. BAILEY.
